    It was the Olympus 70-300. The lens has its foibles & I discarded a lot of shots to get that one but it does perform pretty well when coaxed. I shot that at 239mm (478 35mm equiv) hand held at 1/640s, iso 800, F5.4 from about 2-3 feet away (about as close as it would focus) hence the very shallow dof. Actually I just worked out what the dof was and it was around 1.5mm so no wonder I had such a hard time getting the focus I wanted. I tried several different apertures up to f8 but soon ran out of sensible shutter speeds to hand hold. Even at f8 the dof was only 2.2mm and that halved again if I went up to 300mm!. It's surprised me quite how narrow dof this lens has at long telephoto. I'll have to spend some time with the dof calculator plotting out a little graph as a quick aid. I dont feel so bad about all the oof shots now

    I tend to just use the DOF preview on my camera - it was one of the
    'Got to have's on the list when I got a DSLR - all my previous FSLR's
    had one so I was used to it.
    Yep - there is a fine line of compromise to work with
    Get too close and the Butterfly is off - but closer with wider angle gives
    better DOF
    I am convinced the optimum in terms of my x1.5 calculations - is
    between about 90 and 150mm - aprox 68 - 113 in Oly terms (x2)
    90mm on mine is the old 135 in 35mm film terms
    I am most likely, if I get one, to get the Tamron 90mm macro.
    Although rings - or even a 2x converter are not our of the question.

    Your image looks great to me - I can only say I always had a great respect
    for Olympus / Zuiko glass and I was very close to an Oly when I first went for DSLR - merely the in my hands feel that decided between Nikon, Canon, Oly.

    I Just looked back - I thought I had already posted this - but couldn't find it
    It's the top of an Alium in my front garden.....

    Yep I use the dof preview too but my viewfinder is quite small (even though I use a x1.4 magnifier) & often its quite difficult to judge dof properly. Plus the main problem I had was that hand holding easilly could move the focus position a mm or two if I was a bit slow pressing the shutter all the way. Sometimes I part press look at focus & then full press not a good idea in this situation. Really ought to get the tripod out more
    Lovely alium Geoff. Althouigh it appears a bit on the soft side for you, maybe that's just the resize?

    kgosden - thanks - I was happy too - it came out quite accurate and true to colour (the wonders of getting used to manual white balance!)
    Phil - I know what you mean - I am not home just now to check - but I suspect it would have been f8 - but it depends on the focal length...
    But when I took it I used manual focus as it seemed nearly impossible to get the whole thing nicely sharp - without resorting to much smaller apperture and therefor higher ISO to keep the shutter speed up.
    I used the DOF preview to try to balance out the focus to cover all of it as best as I could
    A tripod wouldn't help here as there is usually a bit of wind in that corner of the garden - so shutter speed needs to stay reasonably quick.

    MPT - nice colours, I like the close focus/shallow depth of field here
